Detailed Description

Read HTK HMM definition file: the main.

This file includes the main routine to read the HMM definition file in HTK format.

This file also contains functions and global variables for per-token reading tailored for reading HTK HMM definition file. The read_token() will read the file per token, and the read token is stored in a global variable rdhmmdef_token. The other reading function will refer to this variable to read the current token.

boolean rdhmmdef	(	FILE *	fp,
		HTK_HMM_INFO *	hmm
	)

Main top routine to read in HTK HMM definition file.

A HTK HMM definition file will be read from fp. After reading, the parameter type is checked and calculate some statistics.

Parameters:

	fp	[in] file pointer
	hmm	[out] pointer to a HMM definition structure to store data.

Returns:

TRUE on success, FALSE on failure.
